Can any other PC/Device on the LAN access the emby server OK ? Are the wifi IP addresses on the same subnet/LAN as the Ethernet devices ? ie are they all something like 192.168.x.y - where the only octet that changes between devices is y ? in powershell (type powershell from a command prompt) - type test-netconnection IP-ADDRESS-OF-SERVER -Port 8096 ie  test-netconnection 192.168.1.10 -Port 8096 what does it show ?
